People working on computers easily feel the tiredness they get due to continuous exposure to screens. But in the digital era it has become mandatory for all to use digital devices of various sizes. Some tend to use these devices for more than an hour. Such exposure to screens for a long duration easily leads to computer vision syndrome in children and adults. Some of the common symptoms are - eye strain, headaches, blurred vision, dry eyes, and neck and shoulder pain, etc. One can easily stay away from this if the some of the steps are followed.
